Description
Technical field：
Optical fiber laser wire feed technical field of laser processing is the utility model is related to, it is more particularly to a kind of to be swept based on wedge-shaped mirrors
Retouch coaxial wire feed in light and laser machine optical system.
Background technology：
Laser processing technology covers a variety of Laser Processing works such as laser cutting, welding, quenching, cladding, punching, micro Process
Skill, make use of the fundamental characteristics of high-order harmonics spectrum.Since laser beam has untouchable, the processing with rapidoprint
For speed soon with the advantage such as good quality, it is a kind of new and high technology that can not be substituted to have established laser processing technology.
Optical fiber laser is due to advantages such as optical fiber pliability is good, electro-optical efficiency is high, small volumes so that optical-fiber laser
Device becomes increasingly conspicuous in the occupation rate of market that industrial lasers are processed.With being greatly reduced for middle high-capacity optical fiber laser price, swash
Photocoagulation, laser melting coating etc. are also progressively widely popularized.
Wire feed laser welding, wire feed laser melting coating are very common in laser welding and cladding, and collectively referred to here in as wire feed swashs
Light is processed.Common wire feed Laser Processing, is broadly divided into two classes, and one kind is the Laser Processing of paraxonic wire feed, and one kind is coaxially to send
Silk Laser Processing.
So-called paraxonic wire feed Laser Processing, vertically or approximately perpendicular to processing base material, wire feed uses this refers to laser beam
There is the lateral wire feeding mode of sharp angle relative to processing base material, the influence in wire feed position stimulated light beam scanning direction, this will lead
Cause that wire feed Laser Processing is each poor to uniformity, and wire feed stock utilization is low, process velocity slowly and processing quality and uniformity very
It is difficult to guarantee.
The processing of so-called coaxial wire feed, this refers to wire feed material relative to processing base material perpendicular or generally perpendicular, laser beam
The mode being then processed around wire feed material.Coaxial wire feed processing is processed relative to paraxonic wire feed, helps to solve wire feed material
Expect utilization rate, process velocity and processing quality and respectively to consistency problem.At present, coaxial wire feed processing mainly includes ring light
Interior wire feed processing is processed with wire feed in light splitting light.
Wire feed is processed in ring light, such as patent publication No. CN 101386111A and CN 104259461A, is substantially adopted
Light beam is divided into 360 ° of annular beams with conical mirror, annular beam is focused on by annular parabolic lens, and focused spot is solid
Point, defocus part are then hollow annular beam.Its problem is that conical mirror, wire feeder, wire feed material etc. are not being kept off
Assembling is difficult to realize under the premise of light；Annular beam only has the defocus section of focused spot and neighbouring very little to be carried out to wire feed material
Processing, defocus is just very scattered apart from somewhat larger energy, so that wire feed rate is difficult then comparatively fast completely to melt wire feed material
Change, and the required precision to wire feed rate is relatively also higher, otherwise influences Laser Processing uniformity；Annular beam is respectively to energy
Uniformity is strictly dependent on conical mirror, inadequate or the incomplete central symmetry of Energy distribution even enters in laser beam circularity itself
Optical position problem is penetrated, it is respectively inconsistent to energy to be all easy to cause annular beam, and then influences Laser Processing；During wire feed,
Inevitably occur wire feed material to deviate hot spot convergent point and cause wire feed material respectively to heated obvious inequality, and cause processing base material
Surface discontinuity；Ring focusing light beam taper checks and balance with wire feeder end to laser convergent point distance, ring focusing light beam
Taper is big, is conducive to the reduction of wire feeder end and laser convergent point distance, but the solid light beam partial-length of laser convergent point
Shorten, and be unfavorable for improving fuse speed, vice versa.
Wire feed processing is divided in light such as 105499793 A of patent publication No. CN, using four beam splitting lenses by incoming laser beam
Focus on after being divided into four bundles light beam, then reflected through the middle speculum with through hole, wire feeder is by mirror via wire feed.Its
Solve the problems, such as wire feed scheme annular beam power dissipation in ring light to a certain extent, and avoid wire feeder and laser
The problems such as beam directly contacts and causes energy loss and wire feeder fever deformation.But its there are the problem of be, four light splitting
The corner angle uniformity of eyeglass extremely difficult rib verticality and light splitting surface for ensureing eyeglass both sides in processing, still more using two panels four
Spectroscope, is easy to cause focus on light beam and is changed into prismatic distribution from preferable square profile, the focused spots of four road divided beams without
Method overlaps to a bit；As annular beam coaxial wire feed scheme, four light splitting focus on light beam tapers and wire feeder ends are to sharp
Light convergent point distance checks and balance, and focus on light beam taper is small, can increase solid light beam section size, but easily leads to wire feeder end
Hold focused spot distant, wire feed material is easily bent so that it cannot be sent to light beam convergent point, on the contrary then solid light beam
Section is very short, and wire feed material and laser beam contact area are small, limits process velocity.In addition, to ensure wire feeder end and laser
Convergent point position is shorter, that is, the light splitting focus on light beam taper of increase four, and second four light splitting lens dimension must be worked into very greatly,
High degree increases machining eyeglass difficulty.
Based on the premises, the utility model proposes one kind based on coaxial wire feed Laser Processing optics in wedge-shaped scarnning mirror light
System, based on scan-type coaxial wire feed concept, based on wedge-shaped mirrors scanning patter diversity and high frequency, based on oblique multi-pass etc.
